Knowledge point
Color-flow imaging
Color-flow imaging is an enhanced form of Doppler ultrasound
technology. In a procedure similar to duplex ultrasound, it uses
color to highlight the direction of blood flow. Vessels in which
blood is flowing are colored red for flow in one direction and blue
for flow in the other, with a color scale that reflects the speed
of the flow.It can clearly understand the anatomical shape and
activity of large blood vessels, and can visually display the
direction, speed, range of blood flow, and whether there are blood
flow disorders and abnormal pathways. The speed of blood flow
determines the reflection frequency, which is represented by
amplitude beam in spectral Doppler. The velocity of blood flow is
fast, and the amplitude on the spectrum curve is high; the velocity
of blood flow is slow, and the amplitude on the spectrum curve is
low, so amplitude can accurately calculate the velocity of blood
flow. Color Doppler images are displayed with different brilliance.
Color Doppler flow imaging
Color Doppler flow imaging system can simultaneously display B-type
image and Doppler blood flow data (blood flow direction, flow
velocity, flow dispersion) of dual ultrasound scanning system.
Color power angio(CPA) detected the backscattered energy of blood
cells in the blood flow, which did not distinguish the flow
direction, and had nothing to do with the angle θ (the angle
between the direction of sound wave and the direction of blood
flow). CPA can improve the sensitivity of blood flow detection,
especially suitable for displaying low-speed blood flow of small
vessels, but can not show the direction of blood flow.
Annular probe
The principle of using the circular ring array dynamic segmented
focusing method in mechanical sector-scan ultrasonic diagnostic
equipment is the same as that of linear array dynamic focusing.
Applying a proper delay to the electrical signal of each element
can achieve focusing at any distance along the central axis, which
is similar to the function of an acoustic lens, so it functions as
an "electronic focusing lens".
